• L19TNF
• Lomustine
• Lomustine

Eligibility

Inclusion criteria

• 1. Male or female, age ≥18.
• 2. Patients with histologically confirmed glioblastoma per 2021 WHO classification progression according to RANO criteria.
• 3. For operated patients, the histological report must document glioblastoma recurrence and a new MRI will need to be done at 3-5 weeks after surgery (directly before study treatment start). Study treatment will need to start minimum 4 weeks after surgery.
• 4. MGMT promotor status known.
• 5. Karnofsky Performance Status (KPS) ≥ 60%.
• 6. Documented negative test for HIV-HBV-HCV. For HBV serology, the determination of HbsAg and anti-HbcAg Ab is required. In patients with serology documenting previous exposure to HBV, negative serum HBV-DNA is required (HBV-DNA is not required for patients with documented vaccination report). For HCV, HCV-RNA or HCV antibody test is required. Subjects with a positive test for HCV antibody but no detection of HCV-RNA indicating no current infection are eligible.
• 7. Female patients: female patients must be either documented not Women Of Childbearing Potential (WOCBP)\* or must have a negative pregnancy test within 14 days of starting treatment.
• Additionally WOCBP must agree to use, from the screening to 6 months following the last study drug administration, highly effective contraception methods, as defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' Clinical Trial Facilitation Group (www.hma.eu/ctfg.html) and which include, for instance, progesterone-only or combined (estrogen- and progesterone-containing) hormonal contraception associated with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion or vasectomized partner.
• 8. Male patients: male subjects able to father children must agree to use two acceptable methods of contraception throughout the study and until 6 months after last study drug administration (e.g. condom with spermicidal gel). Double-barrier contraception is required.
• 9. Personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
• 10. Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.
• Women of childbearing potential (WOCBP) are defined as females who have experienced menarche, are not postmenopausal (12 months with no menses without an alternative medical cause) and are not permanently sterilized (e.g., tubal occlusion, hysterectomy, bilateral oophorectomy, or bilateral salpingectomy).

Exclusion criteria

• 1. Inability to undergo contrast-enhanced MRI.
• 2. Anti-cancer treatment with radiation therapy, chemotherapy, targeted therapies, immunotherapy, hormones, tumor treating fields or other antitumor therapies within 4 weeks prior to study treatment start.
• 3. Subjects who participated in an investigational drug or device study within 4 weeks prior to study treatment start.
• 4. Grade ≥ 4 myelotoxicity with previous treatment of alkylating agents (e.g., TMZ, CCNU).
• 5. Previous treatment with Bevacizumab.
• 6. Previous treatment with L19TNF.
• 7. Previous treatment in the PH-L19TNFCCNU-02/20 study.
• 8. Known history of allergy to TNF, any excipient in the study medication or any other intravenously administered human proteins/peptides/antibodies.
• 9. Absolute neutrophil count (ANC) \< 1.5 x 10\^9/L; platelets \< 100 x 10\^9/L or hemoglobin (Hb) \< 9.0 g/dl.
• 10. Chronically impaired renal function as indicated by creatinine clearance \< 60 mL/min/1.73m2 or for patients older than 65 years without albuminuria or proteinuria, creatinine clearance \< 45 mL/min/1.73m2.
• 11. Inadequate liver function (ALT, AST, ALP ≥ 2.5 x ULN or total bilirubin ≥ 1.5 x ULN).
• 12. INR \> 1.5 ULN.
• 13. Any severe concomitant condition which makes it undesirable for the patient to participate in the study or which could jeopardize compliance with the protocol, in the opinion of the investigator.
• 14. Active or history of autoimmune disease that might deteriorate when receiving an immune-stimulatory agent, in the judgement of the investigator.
• 15. History within the last year of cerebrovascular disease and/or acute or subacute coronary syndromes including myocardial infarction, unstable or severe stable angina pectoris.
• 16. Heart insufficiency (\> Grade II, New York Heart Association (NYHA) criteria).
• 17. Clinically significant cardiac arrhythmias or requiring permanent medication.
• 18. LVEF \<55% or any other abnormalities observed during baseline ECG and echocardiogram investigations that are considered as clinically significant by the investigator. Patients with a marked prolongation of QT/QTc interval (e.g., repeated demonstration of QTc \>470 milliseconds using Fredricia's QT correction formula) are excluded.
• 19. Uncontrolled hypertension.
• 20. Known arterial aneurism at high risk of rupture.
• 21. Ischemic peripheral vascular disease (Grade IIb-IV according to Leriche-Fontaine classification)
• 22. Anxiety ≥ CTCAE Grade 3.
• 23. Severe diabetic retinopathy such as severe non-proliferative retinopathy and proliferative retinopathy.
• 24. Major trauma including major surgery (such as abdominal/cardiac/thoracic surgery) within 3 weeks of administration of study treatment.
• 25. Known active or latent tuberculosis (TB).
• 26. Pregnancy or breast feeding.
• 27. Requirement of chronic administration of high dose corticosteroids or other immunosuppressant drugs. Subjects must have been either off corticosteroids, or on a stable or decreasing dose ≤ 4 mg daily dexamethasone (or equivalent) for 7 days prior to start of treatment. Limited or occasional use of corticosteroids to treat or prevent acute adverse reactions is not considered an exclusion criterion.
• 28. Presence of active and uncontrolled infections or other severe concurrent disease, which, in the opinion of the investigator, would place the patient at undue risk or interfere with the study.
• 29. Concurrent malignancies unless the patient has been disease-free without intervention for at least 2 years.
• 30. Growth factors or immunomodulatory agents within 7 days prior to the administration of study treatment.
• 31. Serious, non-healing wound, ulcer, or bone fracture.
• 32. Deep vein thrombosis, pulmonary embolism or other acute vascular events within 6 months.
• 33. Anticoagulation therapy with P2Y12 antagonists (e.g., clopidogrel, ticagrelor) and vitamin K antagonists (e.g., phenprocoumon, warfarin).
• 34. Requirement of concurrent use of other anti-cancer treatments or agents other than study medication.
• 35. Any recent live vaccination within 4 weeks prior to treatment or plan to receive live vaccination during the study.
